Higher number skills come easy when kids practice with our interactive number lines! Each illustrated board covers numbers 0-100 and features a sliding pointer, so it’s fun to practice adding and subtracting within 100, solving simple word problems, adding and subtracting by multiples of 10, and more! We’ve even included 72 leveled equations for extra practice—complete with answers on back for easy self-checking. You get 10 slider boards; each measures 2 1/2" x 14 1/2".
